The present invention relates to an inoculant for the manufacture of cast iron with spheroidal graphite, said inoculant comprises a particulate ferrosilicon alloy consisting of between about 40 to 80 % by weight Si
0.02-10% by weight Ca
0-15 % by weight rare earth metal
0-5% by weight Al
0-5% by weight Sr
0-5% by weight Mg
0-12 % by weight Ba
0-10 % by weight Zr
0-10 % by weight Ti
0-10 % by weight Mn
wherein at least one, or the sum, of elements Ba, Sr, Zr, Mn, or Ti is (are) present in an amount of at least 0.05 % by weight, the balance being Fe and incidental impurities in the ordinary amount, wherein said inoculant additionally contains, by weight, based on the total weight of inoculant : 0.1 to 15 % by weight of particulate Sb2O3, a method for producing such inoculant and use of such inoculant. |
